Abstract
A reaming shoe for location in a bore has a rotationally balanced nose. A rotary drive is rotationally coupled to the reaming shoe to enable reaming of the bore. The assembly of the reaming shoe and the rotary drive is adapted to be coupled to a tubular component. The reaming shoe is mounted to the tubular component to enable rotation of the reaming shoe independently of the tubular component, such that the reaming shoe is rotatable at a different rotational speed than the tubular component.
